INSTALLATION
Please read Installation Precaution before
installing your Impact HC amplifier, and then
refer to the diagrams provided to connect
power, speaker and audio input connections
according to your own system design.
Installation Precaution
• For safety, disconnect the battery during
installation. Confirm that your head-unit
or other equipment is turned off while
connecting the input jacks and speaker
terminals.
• Select a location inside your vehicle which
has adequate ventilation and protected from
dust and moisture
• Before drill or cut any holes, investigate your
car’s layout very carefully. Take care when
you work near gas tank, hydraulic and fuel
lines, electrical wiring.
• Do not operate the amplifier when un-
mounted. Fix all audio system components
securely within your car to prevent shorts
and damage especially in case of an
accident.
• Do not mount this amplifier so that the wire
connections are unprotected or likely to be
damaged by nearby objects.
• If you need to replace a fuse, only replace it
with a fuse of exactly same type and rating.
• Use proper sized wires to prevent electrical
fire, system damages and to obtain peak
performance.
Amplifier Installation
• Bolt the amplifier to the mounting surface.
Do not mount the amplifier upside down, as
it will restrict airflow over the heat sink.
• Using a 2 AWG, or larger, wire, run a ground
wire from the
GND
terminal of the amplifier
to the nearest chassis ground. Make sure
that the connection to the chassis is rust free
and cleared of all paint.
• Run a wire (same gauge of ground wire)
from the positive terminal of the battery to
the
+ 12 V
terminal of the amplifier. Install
an in-line fuse holder at about 45 cm. (18”)
from the positive (+) terminal of the battery.
• If multiple amplifiers are to be run, and
a distribution block is used, then run the
largest gauge wire from the battery (+)
to the location in the vehicle where the
distribution block is located. Install a fuse
holder (or a circuit breaker) at about 45 cm.
(18”) from the positive (+) terminal of the
battery. This fuse/circuit breaker must be
able to handle the total current of amplifiers
being used. Now, individually fuse each
amplifier after the distribution block at the
amplifier location.
• Using a 12 AWG wire, run the Remote wire
from the
REM
terminal of the amplifier to
the remote output of head-unit.
• Connect the RCA input terminals of the
amplifier to the signal source using top
quality interconnect.
Set amplifiers controls as described in the
system you choose and according to the
wiring diagrams that follow in this manual.
